A new method based on alpha particle track for detection of radionuclides on electromigrated paper.

A new method for the detection of alpha radionuclides on the electromigrated paper has been proposed. The method is based on the alpha particle track detector with celluloid films. Alpha irradiated films are etched in NaOH solution and are compared with the autoradiographs on X-ray films, whereby the alpha nuclides could be easily distinguished from the beta and gamma nuclides. The authors could confirm the half life of the nuclide from measurements of the number of alpha tracks. The method is applicable to the chemical investigation of alpha nuclides, such as actinide elements.
